Table 1 Key metric comparison of proposed modes versus existing modes
From: Electro-quasistatic and resonant cavity car body communication
Technology | Operation bitrate | Max range | Communication medium | Detectable from Chassis (meters) |
|---|---|---|---|---|
CAN | 1 Mbps | Determined by cabling | Single twisted pair | 0 |
LIN | 19.2 kbps | Determined by cabling | Single forward path wire, common ground connection | 0 |
FlexRay | 20 Mbps | Determined by cabling | Single twisted pair, fiberoptic | 0 |
MOST | 150 Mbps | Determined by cabling | Fiberoptic | 0 |
Ethernet | 400 Gbps | Determined by cabling | 4 twisted pairs, typically copper | 0 |
Radiative wireless (Bluetooth, Wi-Fi, 900 MHz, mmWave) | Variable | Variable | Air or dielectric | >12 |
EQS inside excitation capacitive return path [this paper] | 10 Mbps | 1m | Surface | 0 (Fig. 3c) |
EQS outside excitation capacitive return path [this paper] | 10 Mbps | Determined by length of chassis (~4 m) | Surface of vehicle chassis (no additional wires) | ~1 (Fig. 4c) |
Resonant cavity mode [this paper] | 100 Mbps | Determined by perimeter of chassis (~2 or 4 m) | Air or dielectric inside chassis (no additional wires) | ~1* (Fig. 4b) |
